The Hollyland MARS T1000 is a full-duplex wireless intercom system with 1000' line-of-sight transmission range. It includes a base station and four beltpacks. The base station powers from an included AC power adapter with 4-pin XLR connector or from optional L-series batteries via the dual-battery plate built into the top of the station.

The base station supports wireless tally, and it has a built-in OLED screen that displays the status of each beltpack in real-time. In each beltpack, there is a diaplay screen to let us know the details easily. It also has a 3.5mm jack for the included headset and a button that mutes the mics on the beltpacks. The base station has four USB ports for charging the included beltpacks as well as for paired data connection.

The included beltpacks each have an integrated lithium-ion battery for 8 hours of operating time and support charging via a USB port. Each beltpack has a 3.5mm port for a headset/mic combination and a individual mute/call button. It allows up to 10 channels communication with dual-device cascade. This is useful in scenarios where more people join the communication.
